I have written about COB led’s being cooler (the led’s are mounted directly on the heat sink instead of a circuit board) as well as brighter and longer lived… We now have COB technology applied to our strip light fixtures. This replaces the old 1/2 watt x 3 surface mounted led’s. The same manufacturer that makes our amazing 5w MR16s has engineered this product especially for Silhouette. Now you can get COB technology in our rail light, deck lights and path lights. The 1.5w 2800K dimmable strip is equal to a 20w halogen lamp. We have just improved our lighting line-up a giant step up in quality and reliability.
